2021 Miami Open odds, semifinal predictions: Proven tennis expert reveals Barty vs. Svitolina picks

Gavin Mair called Naomi Osaka winning the 2018 U.S. Open at 32-1 and locked in his 2021 Miami Open picks

World No. 1 Ashleigh Barty can move one step closer to successfully defending her Miami Open title when she takes on Elina Svitolina on Thursday in the semifinals of the 2021 Miami Open at Hard Rock Stadium in Miami Gardens, Fla. Two years ago the 5-foot-5 Australian defeated Karolina Pliskova for the title, which then was the seventh of her career. (The tournament was not played last year because of the pandemic.) Meanwhile Svitolina has advanced past the quarterfinals for the first time in eight appearances in Miami.  The match is set to begin at 6 p.m. ET. William Hill Sportsbook lists Barty as a -225 favorite (risk $225 to win $100) in the latest Barty vs. Svitolina odds, with Svitolina listed at +175 as the underdog. You can also pick whether Barty will cover the 2.5-game spread and how many games the match will last, among other wagering options on the 2021 Miami Open tennis odds board. Before making any Svitolina vs. Barty picks, be sure to see the 2021 Miami Open predictions from elite tennis handicapper Gavin Mair. Mair is the international women's tennis expert who called unseeded Jelena Ostapenko (80-1) winning the 2017 French Open, Naomi Osaka (32-1) winning the 2018 U.S. Open, and Bianca Andreescu (20-1) winning the 2019 U.S. Open. Before the women's singles final in the most recent grand slam, the Australian Open, he picked Osaka to win in straight sets (-162) and for the match to go under 20.5 total games (-118), and he was right on both counts.
